RE: 80 yard shot!
No, it's possible but I hope he never takes this shot out in the woods. Back when I shot major competitions I frequently shot at 60 yards and still practice that today because it makes closer shots, chip shots. It makes you concentrate and execute your shots more precise because you have to. Prior to elk hunting I practiced out to 75 yards and was grouping broadheads (Muzzy) close enough to damage arrows and vanes.
Olympic shoots shoot 80 meteres etc...so, it's totally possible.
